Answer:
P(1, B) = 1/12
Step-by-step explanation:
if given one group of 3 objects, in this case tennis balls labeled 1, 2, and 3. And another group of 4 objects, labeled a, b, c, and d. the combined probability would be 1/3 * 1/4 = 1/12. This is because there is a 1/3 chance of picking one particular object from a set of 3 total objects, and a 1/4 chance of picking one particular object from a set of 4 total objects.
Answer:
2x^2 + 5x - 12
Step-by-step explanation:
(x+4)(2x-3)
2x^2 - 3x + 8x - 12
2x^2 + 5x - 12
Answer:
i) 0.872
ii) 0.300
iii) 0.76
iv) 0.704
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $261.50 per month
Standard Deviation, σ = $16.25
We are given that the distribution of monthly food cost for a 14- to 18-year-old male is a bell shaped distribution that is a normal distribution.
Formula:
a) P(Less than $280)
Calculation the value from standard normal z table, we have,
b) P(More than $270)
P(x > 270)
Calculation the value from standard normal z table, we have,
c) P(More than $250)
P(x > 250)
Calculation the value from standard normal z table, we have,
d) P(Between $240 and $275)

e) Thus, 0.704 is the probability that the monthly food cost for a randomly selected 14- to 18-year-old male is between $240 and $275.

1.You can convert them so that they have equal denominators. Then, the numerator can help you decide.
2. Convert them into decimals and compare.
3. Sketching out the fraction that represents wholes and parts.
Here, the numerator of 5/4 was larger than the denominator, unlike 9/10. Subsequently, you can infer that 5/4>9/10
